Meaning of "Hoosier" by reader C. Addleman (submitted 5/3/2014):
I am 54 (born 1960) and this is the story I was told by my 91-year-old mother, as it was told to her by her mother, Laura Winchell Guy (born 1882):
"Indiana homesteaders of the early years were much more casual and less formal than the eastern proper city folk. Rather than going to the door to greet a caller, they kept doing whatever they were doing and loudly yelled; 'Who's there?'
Apparently the person at the door heard this as a friendly welcome and invitation to come on in. It became a funny colloquial slur of the two words ("who's there?") spoken as if something was clamped in their front teeth (a man's pipe or a woman with a sewing needle held in her mouth). Try holding something with your front teeth or lips and say 'Who's there?' loudly to a person outside the front door and they will hear what sounds like Hoosier."
The quote is from my mother BJ Guy Addleman (born 1923) as it was told to her by her mother Laura Winchell Guy (born 1882). That's my story from the 1800's generation. I think it's as close to fact as it can get.
